by Codevolution
Codevolution takes a customer message from the TypeSafe playground into TypeScript, explaining Noul, Choice, and Score responses before combining them in one request. The closing examples make the boundary clear: use Jev for bounded judgments, a text model for writing, and ordinary code for exact calculations.
Duration: 22 minutes 12 seconds.
by codebasics
Codebasics and AI research engineer Siddhant Pandey demonstrate Jev's API and LangChain integration. They explain how Jev functions as a decision and classification model using primitive types like Noul, score, and choice, testing it on insurance processing, model routing, and safety guardrails.
Duration: 17 minutes 6 seconds.
by KodeKloud
KodeKloud explains Jev through support-ticket routing, then builds a Papers, Please-inspired approval game with Claude Code and KodeKey. The most useful section shows how several independent ticket questions can guide escalation even when the department choice remains uncertain.
Duration: 21 minutes 51 seconds.
by Dave Ebbelaar
Dave Ebbelaar builds a Python support-ticket flow, inspects category probabilities, and combines category, frustration, and refund questions in one call. He also explains why sending client data to a new provider needs a separate privacy decision, even when the API is easy to use.
Duration: 16 minutes 50 seconds.
by Telusko Alien Coach
This Python tutorial uses Noul, Choice, and Score questions to route support tickets. It demonstrates request configuration, confidence gates, composite priority scores, and parallel questions that inform a handoff to application code, an LLM, or a person.
Duration: 40 minutes 17 seconds.
by ZazenCodes
ZazenCodes demonstrates how to query TypeSafe's Jev model using the Python SDK. The tutorial covers Jev's core decision primitives—Noul, Choice, and Score—along with parallel multi-question evaluation and an automated support ticket triage loop.
Duration: 20 minutes 58 seconds.
by Moritz | AI Systems
Moritz demonstrates how Jev differs from text-generating LLMs by outputting fast probabilities over predefined options. Using Cursor and the TypeSafe API, he implements three practical prototypes: a real-time voice-controlled browser, an efficient semantic memory lookup system, and a hybrid YouTube title scoring and ranking pipeline.
Duration: 22 minutes 41 seconds.
by Ray Amjad
Ray Amjad explains TypeSafe's Jev model as a fast System 1 probability classifier. He demonstrates its three primitives—Noul, choice, and score—in the web console before exploring agentic patterns like parallel browser testing, dynamic skill selection, qualitative linting, and multi-angle PR review paired with System 2 frontier models.
Duration: 27 minutes 28 seconds.
by LangChain
LangChain product manager Sydney introduces Jev, a System 1 decision model from TypeSafe AI. The video covers how Jev handles parallel typed queries (choice, score, boolean) directly on structured state, contrasting it with LLMs and demonstrating harness use cases like model routing, risky tool call gating, and judge-based evals.
Duration: 9 minutes 14 seconds.
by Steve (Builder.io)
Steve from Builder.io tests Jev on automated browser and OS tasks, revealing significant failure rates when operating on raw text representations without visual input. He demonstrates where Jev fails standalone, how a hybrid fallback with multimodal LLMs works, and practical integration patterns like tool selection and priority classification.
Duration: 5 minutes 30 seconds.
